SWLing Post reader, London Shortwave writes with a remarkable story about the free SDR application, SDR#(or, “SDR sharp”). He writes:
“Two days ago, I emailed Youssef (SDR# developer lead) to ask if he would consider adding synchronous AM detection to his software at some point.
To my great surprise he e-mailed me back the same day and told me that it wouldn’t take him long to write the necessary code. A few hours later he sent me a preview copy of the software with the feature included (all I had to do was to swap one .dll file in the version I had installed at the time). The following day, he integrated it into the latest release!
With the new sync detector the software is rapidly becoming my favourite SDR application.
Here’s a demo video I made for Youssef (and everyone else!) to show how I’ve been getting on with it:
This is amazing–what’s especially impressive is that a first iteration of AM sync should be so well implemented. I love the way you can use the IF shift to block out interference within a sideband, much like USB/LSB selectable sideband. There are paid and OEM SDR applications that can’t do this.
London Shortwave: you’ve convinced me to see if SDR# will drive any of my receivers. Many thanks!
Most impressive! Indeed, I believe SDR#’s noise reduction might rival that of OEM applications. While I’m not the biggest fan of noise reduction for everyday use (due to inherent digital artifacts) it is a valuable tool when noise levels are high.
